Quality Control

Our 17-β-Hydroxyandrost-4-En-3-One Nicotinate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with every shipment, ensuring traceability and compliance with your research or cGMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and away from direct light exposure to maintain stability and purity.
